RICHARD E. BRUNACOI, OF ATTLEBOROUGH, MASSACHUSETTS.

A SLEEVE-BUTTON.

SPECIFICATION forming part of Letters Patent No. 278,772, dated June 5, 1883.

Application filed March 8, 1883. (No model.)

To a. IU/LO'HI/ it may concern Be it known that I, RICHARD E. BRUNACCI, of Attleborough, in the county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in Sleeve-Buttons, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying draw ings, forming a part of this specification, in which Figure 1 is a perspective view of a but-ton embodying my improvement; Fig. 2, a vertical transverse section of the same; Fig. 3, a bottom plan view of the shoe; Fig. 4, a side elevation, showing the button with its shoe detached; Fig. 5, a top plan view of the lining of the shoe, showing the locking device -or catch Fig. 6', a bottom plan view of the lining, showing the spring and catch; and Fig. 7, an enlarged vertical section, showing the ej ectingspring and washer.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of sleeve or cnff buttons which are separable, or so made that the body and shoe may be detached to enable the button to be readily inserted in or removed from the button-hole; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more effective device of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the body of the button, which is provided with a shank, B, having the circumferential groove m at its inner-or free end.

The shoe consists of two annular plates or disks, 0 D, the plate 0 forming the body of the shoe, and D its lining, these parts being attached or secured together by turning or milling the edge or periphery of the body down over the lining, as best seen at a in Fig. 2. Projecting upwardly from the center of the disk D, and arranged vertically to the plane thereof, is a short tube or sleeve, E, open at itsouter end, and designed to receive the shank B when the button is in use, or its parts coupled, as shown in Figs. 1 and 2. The disk 0 is of slightly greater convexity than the disk D, so that when these parts are attached a space is left between the same in which the evolute spring (Z is arranged, the end at of said spring being secured to the under side of the disk D, asshovni in Fig. 6. A hole or slot, 1 is cut through one side of the sleeve E, near the disk D, and arranged to slide laterally on this disk there is a catch, G, consisting of a small metallic plate having an elongated central slot, f,

through which the sleeve E passes, and provided with an inwardly-projecting horizontal stud, g, which passes through the hole tin the sleeve and enters the groove as in the shank B. The disk D is provided with two elongated slots, h j, and projecting downwardly from the catch G, through the sloth, there is a stud, Z, against which the free end of the spring (1 acts expansively to force the stud 9 into the groove 00. At the opposite end of the catch G there is also a stud, y, projecting downwardly through the slot j in the disk D and a slot, 1), in the disk 0, this stud terminating in a small flattened knob on the outer face of said lastna ned disk, as seen in Fig. l.

The lower end of the shank B is slightly convex or rounded, as shown in Fig. 4, so that when the shank is inserted in the sleeve E and pushed down into contact with the inwardlyprojecting stud g the stud will be forced out of the path ofthe shank and fall into the groove 00, after the end of the shank has passed the stud, thereby interlocking or coupling the parts in a manner which will be readily obvious without a more explicit description. 6

In removing buttons of this class from the cuff or sleeve both hands are usually employed, one in holding the cuff and the other in operating or pushing back the catch, rendering it inconvenient to detach the shoe from the body of the button, even after they are uncoupled. To obviate this difficulty I make use of an ejector consisting of the coiled spring 2 and collet or sliding washer k, disposed around the shank B in the interior of the body A, the inner end of the spring abutting-against the plate 1' and its outer end against the collet, which rests on the inner side of the plate H, or back of the button. This plate is provided with a hole, at, at its center, through which the shank B and sleeve E pass, the sleeve being constructed of such a length that in coupling the button to its shoe the sleeve will pass through the hole against the washer k and compress the spring 3 as shown in Fig. 2.

The washer k may be dispensed with, if desired, although it is preferable to 'use it, as it closes the hole n when the sleeve is withdrawn, and affords a bearing for the outer end. of .the spring 1). The plate H may also be omitted; but I deem it preferable that it should be employed.

To detach the shoe from the body ot' the but ton the stud 'y is pushed back by its projecting knob, overcoming the spring (I and disengaging the stud from the shank B, thereby suddenly releasing the spring p and permitting .it to eject the shank from the sleeve E, after which the sleeve may be readily withdrawn from the button-hole.

It will be obvious that the construction described will aft'ord an exceedingly simple, strong, and durable button, the parts of which are not liable to breakage or derangement in use, and which may be easily repaired when broken or out of order.

Having thus explained my invention, what I claim is-- 1. In a separable button, the following instrumentalities, to wit: a body having a shank provided with a circumferential groove or equivalent means for connecting it with a locking-catch, a shoe consisting of an outer and an inner disk joined at their edges, a sleeve attached to the shoe and adapted to receive said shank, said sleeve being provided with a slot .through which a portion of the catch may pass, a spring disposed between said disks, and a sliding catch disposed on the outside of said in- .ner disk, said catch being connected with said spring and adapted to engage said shank, and also provided with a push-stud or means for disengaging the catch and shank, substantially as specified.

2. In a separable button, the catch G, provided with the central slot, f, and studs Z 3 g, in'combination with the disk D and springd, substantially as described.

3. In aseparablebutton,the spring p,washer 7c, shank B, plate H, and'sleeve E, constructed, combined, and arranged to operate substantially as described.
